I have just installed Lubuntu in an old PC, at first try I used the normal iso installer, but after select the language and hit install, I could not see the installation wizard because of the screen resolution. Well, I could solve this selecting nomodeset (in F6 menu) and typing xforcevesa Then the installation wizard starts without problems but my CD had a problem and then I could not complete the installation. Then downloaded the alternate install and the installation completes perfectly, but... once again, I have the screen resolution problem and even can't log in. (see the image attached, there you can see the problem).
I looked for a solution and I found some threads about xrandr (here: https://wiki.ubuntu.com/X/Config/Res...s_persistently ) but when I type xrandr in terminal (I did Ctrl+Alt+F1 to switch from the graphical mode to terminal) I get the message: "can't open display" also I looked for a xorg.conf file and I didn't found anything.
So, now I don't know how to solve and how to search for solutions to my problem.
All the help you can bring me would be really appreciate!!
Thanks in advance!!
